KMBox, MakCU or Arduino: which mouse device for DMA aim
4 min read, updated 1 November 2026
A DMA setup can see everything, but it cannot press anything on the gaming PC by itself. Aim, triggerbot and recoil control go through a small device that pretends to be your mouse.
Why a separate device
Your real mouse plugs into the device, the device plugs into the gaming PC. The gaming PC only ever sees one mouse. The second PC tells the device to add small movements or clicks, which arrive like normal mouse input.
The options
- KMBox Net: controlled over the network. Easy to place anywhere, and it can report which mouse buttons you hold, which the aim key settings use.
- KMBox B+ Pro: controlled over USB serial. A common, well-known choice.
- MakCU: small and fast over USB serial. QOWED connects to it automatically and reads its button state.
- Arduino: the budget route. A board with USB host support, flashed with mouse firmware. Cheap, but you set it up yourself.
Which one to pick
If you want the least setup, take a MakCU or a KMBox. If you already own an Arduino and like tinkering, it works too. All of them run through the same Devices page in the QOWED menu, so you can switch later without changing anything else.
Whatever you use: turn the smoothing up and the FOV down until the aim looks like you on a good day. Snapping across the screen is what gets noticed, not the device.
